Battery life cycle - 1847

[Patrick-32]

I have a MBP late 2011.

iStat pro says battery life cycle is at 1847 and 84%/

Should I replace it, also I've read batteries can expand and bending the top case,is that correct? is it a common fault or is it a specific macbook version?

Is 1847 too much?

With battery health at 84%, I don't see why you would want to replace it.
My 2011 (15") MPB has 66% battery health. I usually have it plugged in, even when I am using it in a library. It has only 210 cycles but only 66% battery health.

I don't see a need to replace mine yet, not until it gets down to 50% or less. Hopefully SkyLake version of MBP will show up before I have to replace my battery though.

I don't see any need to replace it until it either has unacceptably low battery life on a charge or OS X reports that it should be replaced. Yours is still healthy and there's no reason to think it will fail anytime soon - much less explode, expand or bend anything.

From this and other threads I get the impression that battery cycles and health do not have a strong relationship.
